For those lucky people upgrading to iOS8, Apply is offering a Great Free Books promotion. I hear the offer is being extended in multiple countries and languages, although I haven’t independently confirmed that. Obviously, different titles will be offered in different places as copyright law allows. Here’s a link to the U.S. offer. (The link will open iTunes.) In other countries, you should be able to simply open iTunes, go to the Books menu, and find information there. Happy reading!
